This report describes the results of the 2006 field season for the Central Alaska Network (CAKN) flowing waters monitoring program. The key objectives for the 2006 field season were to assess the logistics involved in various sampling approaches and to collect data from a variety of streams as a way to begin to determine the range of natural variability for various candidate biological, chemical and physical metrics. I was able to collect data at 13 study sites located throughout WRST. Two of these sites were visited in two different seasons (summer and autumn) to assess seasonal variability, which was substantial for invertebrates and diatoms and moderate for water chemistry parameters. At one of these sites, multiple replicate biological [...]
